China NMPA Product Recall - Arm-type electronic blood pressure monitor

Guangzhou Tongsheng Electronic Technology Co., Ltd. initiated a voluntary Class 3 recall of its Arm-type Electronic Blood Pressure Monitors, as announced by the National Medical Products Administration (NMPA) on December 25, 2018. This action followed a finding that the product's instruction manual failed to meet technical standards, specifically regarding the description of heart rate measurement. The main issue identified was an omission in the manual to clearly state that common heart rhythm disorders, such as premature atrial contractions, premature ventricular contractions, or atrial fibrillation, could result in inaccurate or unmeasurable blood pressure readings. The company, operating under the NMPA's regulatory framework in China, took prompt corrective actions. On September 28, 2018, Guangzhou Tongsheng Electronic Technology Co., Ltd. recalled the instruction manuals for 54 units of affected products from production batch Q18314A1. Subsequently, on October 15, 2018, revised and compliant instruction manuals, which now explicitly detail the limitations concerning heart rhythm disorders, were reissued to all affected customers. These measures ensure improved user awareness regarding device accuracy limitations.
